Read and answer the question Hi! My name is Alex and I'm eleven years old. My best friend is Mark and he is thirteen. Mark is really talented and has many abilities. He can draw amazing pictures and paint beautifully. Also, Mark loves playing football and basketball. But there's something I can't do yet - ride a bike properly. I often fall down trying to balance it. Mark helps me practice sometimes but still, it's hard for me. Another thing we don't know how to do together is cooking dinner. Our parents say we're not ready yet. Answer the questions according to the text: 1. How old is Alex's best friend? 2. What does Mark like doing in his free time? 3. What activity does Alex struggle with? 4. Why can't they cook dinner themselves? 5. Is there anything else they want to learn?
